Abstract
- This work was to evaluate the effect of in vitro storage temperature and age of males on turkey spermatozoa motility. For this purpose samples were collected from British United Turkeys (BUT) Big 6 line and semen quality was assessed by using Computer Assisted Semen Analyzer (CASA) system. After 60 minutes of storage spermatozoa motility, progressive motility and amplitude of lateral head displacement decreased significantly both in 4° and 41°C regardless of birds age. However the lowest values of all parameters were noted after storage in thermostat. Spermatozoa motility after 0 and 60 minutes in 4°C was higher in samples collected from turkeys of 35 – 42 weeks of age (60.94% and 53.33% respectively). Whereas the value of that parameter in semen stored in 41°C was lower in that age group. The same tendency was found in progressive motility. The results showed that higher temperature of in vitro storage (even that similar to animal body temperature, in this case 41ºC) has more negative effect on spermatozoa motility parameters than lower temperature.
